This presentation addresses the correlation between subjective and objective evaluation in vehicle dynamics assessment. It begins by outlining the main limitations of physical subjective evaluation. Subsequently, it introduces a systematic solution: a correlated virtual environment that integrates high-fidelity vehicle, tire and proving ground models. A detailed case study is then presented to demonstrate how systematic variations in key tire performance parameters directly influence subjective ratings. Finally, the presentation discusses approaches to analyze variability and preferences among different evaluators, exploring methodologies for translating subjective perceptions into actionable engineering targets.

• The critical limitations of relying solely on physical testing and why a virtual approach is essential for vehicle development
• A framework for constructing a correlated virtual evaluation environment to accurately simulate real-world behavior
• How specific, isolated tire mechanical parameters directly influence subjective scores, moving evaluation from art toward science
• Strategies to quantify human evaluator variability in scoring style and preference, enabling more consistent and target-driven development
